Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connector inspection device for inspecting the attachment state of pins of a connector.

In order to prevent malfunctions of conventional connectors, it is necessary to check the mounting state of the pins arranged vertically and horizontally within the connector. Conventionally, this confirmation work was carried out by visual inspection by inspectors, but this method was inefficient and resulted in inspection errors, so in recent years, devices that inspect the attachment condition of connector pins have been put into practical use. With this type of connector inspection device, inspection work can be automated, improving work efficiency and accuracy.

Problems to be Solved by the Invention However, with the above-mentioned conventional connector inspection devices, dedicated devices must be used for each type of connector with different versions of connector pins, so purchasing all connector inspection devices is expensive. The problem was that it was expensive.

The present invention has been made to solve the above-mentioned problems, and aims to reduce manufacturing costs and purchase costs by providing a connector inspection device that can be used with various types of connectors having different numbers of connectors.

Means for Solving Section M In order to solve the above problems, the present invention provides a connector holding unit that holds the connector to be inspected, and provides insertion holes extending in the axial direction of the connector pins in the connector holding unit vertically and horizontally. A plurality of rows are provided in each insertion hole, and movable contact pins are provided in each insertion hole, one end of which is in contact with the connector pin, and the contact pins are movably movable relative to the connector holding unit in the axial direction of the connector pin. A plate portion is provided, one end of which can be fitted into each insertion hole of the connector holding unit, and all movable pins in multiple rows in vertical and horizontal directions are urged toward the connector holding unit by a spring member, and a holder is attached to the movable plate portion. The movable plate portion is provided with a plurality of vertical and horizontal fixed pins that are located near the other end of the movable pin and come into contact with each other as the movable pin moves, thereby preventing contact between each fixed pin and each movable pin. It is equipped with a control device for detection.

Effect: With the above structure, the connector to be inspected is held by the connector holding unit, and the movable plate portion is moved toward the connector holding unit. Then, one end of the movable pin movably provided in the holder on the movable plate portion is inserted into the insertion hole of the connector holding unit and abuts against the connector pin via the abutment pin. When the connector pin is properly attached to the connector, the movable pin contacts the connector pin and then the VC is restricted in position and does not move. Therefore, as the movable plate further moves toward the connector holding device, this movement fV -}, the fixed pin that is moving comes into contact with the other end of the movable pin. If this contact is not detected by the control device, it is determined that the connector pin is properly attached. On the other hand, if the connector pin is not attached to the connector9 or the attachment condition is poor, the movable pin will continue to move more than a predetermined amount even after it is inserted into the insertion hole in the connector holding unit, and the fixed pin and movable pin will do not make contact, and the control device determines whether the connector pin is improperly attached without detecting contact between the fixed pin and the movable pin. Here, even if the number of connector pins differs, the distance between adjacent connector pins is almost constant, so
By providing a large number of rows of pins on the movable plate, that is, movable pin buttons and fixed pins, the members on the movable plate can be used for various types of connectors, and by simply replacing the connector holding unit, We can conduct inspections of various connectors.

central example Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figs. 1 to 4, 1 is a base, and a connector holding unit 10 is fixed to the base 1 with bolts, etc., and a connector holding unit 10 that slides on the V-A/2 extending in the direction a is attached to the base 1. A moving section 20 that is moved by the cylinder section 3 is provided. The connector holding unit l-10 has a mounting recess 1l formed in the upper part for housing and supporting the connector 4t to be inspected, and a block member l2 is mounted at a location facing the mounting recess 11. The connector 4 is arranged in the mounting recess 11K so that the axial direction of the connector pin is in the direction a, and the block member 12 is provided with a plurality of rows and columns of insertion holes 13 extending in the axial direction of the connector pin (direction a). It is being An abutment pin 14 is disposed in each insertion hole 13 so as to be movable in the direction a, and a pressure H of the abutment pin 14 is provided.
It is biased in a direction away from the connector 4 by a spring l5.

The moving part 20 is provided on a moving plate 21 that is substantially L-shaped when viewed from the side, and a guide member 22 that engages with the rail/I/2 is attached to the lower surface of the moving plate 21. Movement 7”L/
-} On the side of the connector holding unit 10 which is hung on the connector holding unit 21, a grounding copper hodder holder is attached which has multiple rows of connecting holes extending in the direction a, and this copper hodder 24
A movable pin 25 is disposed in each Ita hole 23 so as to be movable in the direction a. And does this movable pin 25 have a spring member? It is urged toward the connector holding unit IO side, and one end thereof is fitted into the insertion hole 13 of the block member 12 with an appropriate distance from the abutment pin 14. A bracket holder 27 made of a never-green material is attached to the center side of the movable plate 21.
There is also a vtd hole 28 in the vertical column. A fixed pin 29 is embedded in each of the through holes 28, and one end of each fixed pin 29 is positioned so as to face the other end of each movable pin 25. Each fixing pin 29 is connected to a control device (not shown) via a connecting pin 30 and a connecting cord 31. In addition, if 32 is a mobile gate 21
There is a stopper block T6 that regulates this.

Next, the connector 0@ inspection order will be described. First, the connector 4 is set in the mounting recess 11 of the connector medical holding unit 10, and the pins of the connector 4 and the abutment pins 14 are made to face each other. Next, the cylinder part 3 is driven to move the movable plate} 21 along the V-rule 2 to the connector holding unit 10.
{Move to fill (a, direction). For this movement, first, the movable pin 25 attached to the copper holder 24 via the spring member 26 comes into contact with the abutment pin 14, and then the abutment pin l4 is pressed by the movable pin 25 and resists the compression spring l5. and move in the a1 direction.

Then, each contact pin 14 comes into contact with the connector pin. Here, in the place where the connector pin is properly attached to the connector 4, the movement in the direction a is regulated by this connector pin. The movable pin 25 stops. When the moving plate 21'fK:a1 is further moved, the fixed pin 29 comes into contact with the movable pin 25. Due to this contact, conduction is established between the connection cord 31, the connection pin 30, the fixed pin 29, the movable pin 25 button, and the ground copper holder, so the control device detects this conduction state. It can be determined that the connector pins are installed in a good condition.
